Primary vascular neoplasms of lymph nodes in the dog

Primary vascular neoplasms of lymph nodes are rare, and appear not to have previously been reported in domestic animals. This report describes hemangiomas and a lymphangioma in lymph nodes of aged Beagle dogs. Eight hemangiomas (4.8%) and one lymphangioma were present in 165 examined popliteal lymph nodes, and one hemangioma occurred in a hepatic lymph node. The hemangiomas were cavernous and benign.
